sAsH-FASTENER.

SPECIFICATION forming part of Letters Patent N0, 266,799, dated October31, 1882.

Application filed September 11, iSSQ.

To all whom it may concern:

Be it known that I, LoUIs FELsBURG, ot New Haven, in the county of NewHaven and State of Connecticut, have invented a new Improvement in Sash-Fasteners5 and I do hereby declare the following, when taken inconnection with accompanying drawings and the letters of referencemarked thereon, to be a full, clear, and exact description ofthe same,and which said drawings constitute part of this specification, andrepresent, in

Figure 1, a side view; Fig. 2, a top view with the covering removed;Fig. 3, a transverse section through the locking-lever; Fig. 4, thefastener as applied to use.

rIhis invention relates to an improvement in that class ofsash-fasteners which are designed to be arranged upon the top of theupper bar 0f the lower sash, with. a locking mechanism which will engageboth the upper sash and the jamb, whereby not only will the two sashesbe locked together, but also locked to the jamb, and in any desiredrelative position, as open or closed, andso that disconnecting one sashfrom the other also disconnects the locking mechanism from thejamb; andthe invention consists in the details of construction of the fastener,as hereinafter described, and more particularly recited in the claim.

A represents the case, which is of rectangular or any suitable form, andconstructed to be attached to the top bar, B, of the lower sash,as seenin Fig. 4. Longitudinally through the case is the bolt C, which projectsoutward through the jamb end to form the nose a, and at the other end isprovided with a suitable handle, D, by which itmay be moved. A spring,E, inside the case on the boit, serves to force it forward into itslocking position, and so that in drawing the bolt, as seen in brokenlilies, Fig. 2, the spring will be compressed.

F is a transverse belt, its nose b projecting' throughI the case on theback side, and so as to enter the upper sash, Gr, as seen in Fig. 4.

rlhe principal bolt C is constructed with a diagonal rib, d, which worksin a corresponding diagonal groove in the bolt F. rlhe bolt F is freefor movement in the direction of its axisthat is7 at right angles to theprincipal bolt. Hence, as the principal bolt is moved in one directionor the other it will, because of (No model.)

the inclined rib d working' into the transverse bolt, impart a movementto that bolt F at right angles to the axis ot' the bolt C to the extentof the inclination of the rib d. The normal condition ot' the nose ofthe bolt F is thrown out, as seen in Fig. 2. The drawing of the bolt Calso draws the bolt F inward, as seen` in broken lines, Fig. 2.

' rlhe mechanism is inclosed within the case in the usual'nianner forsecuring like mechanism in other classes oflocks. It is secured upon thetop of the lower sash by means of screws or otherwise, and a hole islnade in the jamb corresponding tothe nose a ot' the bolt C, and asimilar hole into the stile ofthe upper sash, G, corresponding to theend b of the bolt F, as seen in Fig. 4, and so that the spring ofthebolt, when the parts are in their proper relation to each other, willthrow the two bolts respectively into the jamb and into the upper sash,which will not only lock the two parts together by means of the nose ofthe bolt F, but` will also lock the two to thejamb by means of the nosea of the bolt C. The jamb may have several holes in the path of the boltas the lower sash is raised, and `the stile of the upper sash may alsohave several holes in the path of the transverse bolt, so that thelower' sash may be raised to any desired position and there engage thejamb and upper sash; or the upper sash may be lowered to any desiredpoint and engaged by its bolt, or the lower sash may be raised and thesash dropped to a certain extent and there engaged.

In order to loch the bolt to prevent the possibiliry of tampering withit from the outside, I arrange a locking-lever, H, in the case, pivotedat one end, as at c, the other end provided with a stud extendingthrough a slot in the case, and there furnished with a suitable handle,L, by which the lever may be turned upon its pivot, as seen in brokenlines, Fig. 2. The lever is provided with a finger, 7L, which engages acorresponding notch in the bolt. A spring, I, serves to press the levertoward the bolt and into engagement therewith. Then it is desired tounlock the bolt the linger h is withdrawn by turning the lever H, asindicated in broken lines, Fig. 2. In that condition the bolt is freefor movement in either direction, and is locked when the bolts arethrown into IOO engagement with thejamband sash. A noteh in the bolt mayalso be provided, with which the finger h will engage when the bolts aredrawn, so as to `hold the bolts in their withdrawn condition and leaveboth sashes free to be moved.

I have described my fastener as applied so that the principal boltenters the jamb and the transverse bolt the sash. It Will beevident,however,tl1atthisordermay be reversedas, for illustration, thefastener in Fig. 4 may be plaeedat the opposite side of tbe lower sash.Then the nose b would enter the jamb and the nose a will enter the stileof the upper sash.

From the foregoing it will be understood that I do not claim broadly asaslrfastener attached to the lower sash and provided with spendingtransverse movement to the bolt F 3o and the locking lever H,substantially as described.
